Dr Thomas Waite from Public Health England said: "Much of the advice on beating the heat is common sense and for most people there's nothing to really worry about. If you're able, ask your friends, family and neighbours if they need any support".

MeteoGroup forecaster Callum Stewart said: "The highest temperature recorded last night was 24C at London City Airport".

In response to the extreme hot weather, Simon Bottery, director of policy at Independent Age, the older people's charity said: "Older people can suffer adverse effects on their health during the hot weather and can be more vulnerable to heatstroke, heat exhaustion and dehydration".

"However, fresher conditions will move in from the northwest into Thursday".

With the hot weather also comes a warning of a very high pollen count and high UV levels this week.
